如何在JavaScript中将对象{}转换为键值对的数组[]

javascript

我想这样转换一个对象：

{"1":5,"2":7,"3":0,"4":0,"5":0,"6":0,"7":0,"8":0,"9":0,"10":0,"11":0,"12":0}

分成键值对数组，如下所示：

[[1,5],[2,7],[3,0],[4,0]...].

如何在JavaScript中将对象转换为键值对数组？

您可以使用Object.keys()和map()执行此操作

var obj = {"1":5,"2":7,"3":0,"4":0,"5":0,"6":0,"7":0,"8":0,"9":0,"10":0,"11":0,"12":0}

var result = Object.keys(obj).map(function(key) {

  return [Number(key), obj[key]];

});



console.log(result);
